IMPROVEMENT INBOBBlN-HOLDE'RS FOR SPINNING-MACHINES.

Specication forming part of Letters Patent No. 155,558, dated September 29,1374; application filed May is, 1874.

To all whom it may concern Be it known that I, JULEs C. WELLENs, formerly of Brussels, Belgium, but now residing at Philadelphia, Pennsylvania, have invented an Improvement in Tubular Bobbin- Holders for Spinning-Machines, of which the following is a specification:

The object of my invention is to secure a bobbin` to its tubularholder by forming longitudinal slits in the latter, so that, When rapidl rotated. it shall be caused to` expand by centrifuga action, and to us bipdtagainst the interior of the bobbin, all as fully described Y hereafter, and as illustrated by the sectional Ordinarily the bobbin F is prevented from turning independently of the tubular holder and Whirl by a pin on the latter adapted to a hole inthe lower flange of the bobbin.

l'.Ihe principal objections to this plan are, that time is lost in effecting the adjustments, and that the bobbin frequently works loose from its holder, thus producing waste, or necessitating a stoppage of the machinery.

These objections I entirely overcome by forming longitudinal slits a in the tubular bobbin-holder E, as shown in Figs. l and 2, so that, when the said holder is rapidly rotated, its slit portion will become sufficiently expanded by centrifugal action to bind against the interior ofthe bobbin, as,` shown in Fig. 3, and to thus firmly hold the same, While, when the motion is stopped, the said holder will contraet, as shown in Fig. l, and offer no obstruction Whatever to the removing and replacing of the bobbins. Less power is also required to drive my improved bobbin-holder, as there is no copstgact of the expanded portion with the statigpary spipt'ile. When desired, the bobbin can also be adjusted to the holder in an inverted position, and a paper bobbin can be used directly upon the expanding holder, Without requiring an intermediate Wooden tube, as usual.

I claim as my invention- The combination of a tubular bobbin-liolder, split longitudinally, and a bobbin having al1 opening so much greater in diameter than the holder, that the two will revolve together only when the holder is expanded by centrifugal force, as specified.

In testimony whereof I have signed my name to this specification in the presence of tWo subscribing Witnesses.
